Well you could create a profile for all players that are going to play first in the xbox dashboard.
Use the splitscreen option when looking for a game.
I usually have people press start in the lobby right before a game and it will ask you which profile you would like to load for them. they press a then bam they're in the game also. You can do this for up to four players.
You don't have to create a profile for each one but then they would share your name.
Like this Player 1 would be : Chuxty
and Player 2 would be : Chuxty(1)
either way should work.
If it's incoherent then that's cuz I need to stop drinking.
